I have been treating her for canker with metronidazole for 10 days and showed no improvements.Tried oxytet for 7 days and no change. All the while it’s tripled in size in just a month so whatever it is it’s growing fast. The scabs on her comb she’s had for over a year. We’ve tried everything on that as well and it doesn’t seem to clear up. She’s 4 years old seems to be feeling great. She’s the matriarch of the flock and hasn’t slowed down a bit. She also has pink eye in one eye and sounds a little hoarse. I got teramicyn for her eye today. I’ve been treating her eye with vetricyn and it wasn’t helping just loosening it in the morning because it’s sealed shut. I hope it’s not cancer cause other then swallowing funny it doesn’t seem to bother her. I’ve attached some pictures. She’s been free ranging so there’s lots of dirt and debris in her mouth and some of her food.
